Its about time we see better sensor with equal d/r to Sony
That is the main issue for me 65 af points or 200 is not really that important (for me)
As was asked on http://photo.stackexchange.com …-huge-number-of-af-points
- "Nowdays flagship DSLRs have huge number of AF points. For instance Nikon D800 has 51, Canon 5D Mark III has 61. What is the advantage of this? Does using 51 AF points really increases the chance that the camera finds out my intention and focuses on my real subject instead of something else next to it?"
- ...and the reply comes back about focus with less recompose, and better tracking as subject moves across the frame.
- So the next question comes, "Yes, but how of a difference does it make in practice between having say 399 focus points (in the A7R II) vs 100 (in my NEX-5R)? At what point would you say further improvement isn't noticeable in normal use...the kind of photos people take normally: landscapes, portraits, street scenes, nature, cityscapes, night photography, and so on. Does 399 vs 100 focus points make a difference for these? "
- ...and a reply comes back, "A large number of control points allows them to be packed densely, so that a moving target moves smoothly from one point to the next, without falling into a gap."
To which I counter with some additional questions, "Yes, having AF points spread over a larger total area of the frame certainly is better than AF points more tightly clustered around the central area..."
- but if there are 151 AF points vs. 51 AF points spread over the same area, what truly is the benefit if I am not trying to track a bird flying out of my frame, but merely a running 6 year old grandchild who already covers multiple AF points at the same time (even when there are only 51 to choose from)?
- and if I set all AF points active, if I had a 1:5 chance of the camera choosing properly, what 'benefit' arrives concurrant with 120:151 probability of wrong AF point selection (vs. 40:51)?
- and if I have to manually select a single AF out of a cluster zone (of perhaps 10), so that there is no error in AF point auto selection by the camera, it would seem it is more time consuming and laborious (assuming 20% of the AF points in the same cluster zone) to chose from 1:30 rather than 1:10 AF points in that vicinity...what alleviates that issue?
Since I have not upgraded bodies in a very long time, I want to better understand what some of the reasons would be to prompt an update of equipment to a newer body. AF points is one of them.
